The data was analyzed by Horace Dediu of Asymco and he came up with this fairly stunning chart comparing the iPad and Samsung’s tablet offerings. It truly illustrates what people mean when they say that the tablet market is really an iPad market.

Samsung sold around 1.4M Galaxy Tab units in the U.S. between June of 2010 and June of 2012. Apple has sold 34M iPads in the U.S.. While both companies also sold their wares worldwide, the U.S. numbers alone are pretty shocking.

We’ve talked about the dominance of the iPad in the past, and the possibilites that Apple has to truly define a small tablet market with a smaller iPad mini. A number of factors contribute to the iPad’s success, including Apple’s profit margins and supply chain, its software integration and its Retail Stores, which provide a guaranteed high-quality conduit for iPad sales.

Only recently have we seen a tablet capture any significant mindshare in the public, and that’s Google’s Nexus 7, made by Asus. We found it to be a very nice Android tablet, perhaps the best ever. It’s sales haven’t really had a chance to register yet, but there could very well be some competition there. Amazon has yet to release any numbers for the Kindle Fire, so that’s an unknown quantity.

Also, be sure to check out Dediu’s great analysis of the rest of Samsung and Apple’s numbers, including iPhone sales, it’s epic.
